I don't know what are the correct terms for this question. Which form is correct for cases of multiple plural nouns, both should be plural or only the second one, for example:

product prices


products prices

or even maybe:

products' prices

  • This particular example may not be covered in previous threads. I'll just mention that (1) it's unusual (though not unknown where sensible: dogs home; working mens club) for plural nouns (especially hybrids like mens) to be chosen as attributives; (2) particular cases can be looked up on the internet. – Edwin Ashworth Dec 10 '14 at 1:23
